The following principles of appropriate antibiotic use for adults with acute rhinosinusitis apply to the diagnosis and treatment of acute maxillary and ethmoid rhinosinusitis in adults who are not immunocompromised. Most cases of acute rhinosinusitis diagnosed in ambulatory care are caused by uncomplicated viral upper respiratory tract infections. Bacterial and viral rhinosinusitis are difficult to differentiate on clinical grounds. The clinical diagnosis of acute bacterial rhinosinusitis should be reserved for patients with rhinosinusitis symptoms lasting 7 days or more who have maxillary pain or tenderness in the face or teeth (especially when unilateral) and purulent nasal secretions. Patients with rhinosinusitis symptoms that last less than 7 days are unlikely to have bacterial infection, although rarely some patients with acute bacterial rhinosinusitis present with dramatic symptoms of severe unilateral maxillary pain, swelling, and fever. Sinus radiography is not recommended for diagnosis in routine cases. Acute rhinosinusitis resolves without antibiotic treatment in most cases. Symptomatic treatment and reassurance is the preferred initial management strategy for patients with mild symptoms. Antibiotic therapy should be reserved for patients with moderately severe symptoms who meet the criteria for the clinical diagnosis of acute bacterial rhinosinusitis and for those with severe rhinosinusitis symptoms-especially those with unilateral facial pain-regardless of duration of illness. For initial treatment, the most narrow-spectrum agent active against the likely pathogens, Streptococcus pneumoniae and Haemophilus influenzae, should be used.

A randomised placebo controlled double-blind cross-over trial was performed on twenty healthy adults to assess the effect of osmolality (300,600,850 and 1100 mOsm) on local tolerance of an intramuscular injection (0.5 ml) of five suspensions containing the same components as the excipients of a combined Diphtheria-Tetanus-acellular Pertussis-inactivated Poliomyelitis-Haemophilus influenzae type b paediatric vaccine (DtacP-IPV-Hib, PENTAVAC). The results did not show any dose-effect relationship between burning or pain sensations and the different osmolalities tested. Although mild and not clinically relevant, these sensations seemed to occur more frequently following injection of an isotonic saline solution (P<0.05). Thus, the osmolality of vaccine like suspensions does not appear to be a potential cause of local pain or burning sensation after their administration.

An open, randomised, multicentre trial was performed to assess the reactogenicity and safety profile of the administration of a candidate Haemophilus influenzae type b (Hib) conjugate vaccine with a quadrivalent diphtheria-tetanus-acellular pertussis-hepatitis B (DTPa-HBV) vaccine as a single injection (Group 1) versus the simultaneous administration of the latter vaccine (DTPa-HBV) and an available Hib conjugate vaccine (Group 2) in opposite thighs, as a primary vaccination course to healthy infants at 2, 4 and 6 months of age. Eight hundred and eighty five infants (9.3+/-1.4 weeks old) were randomly allocated to Group 1 (n=665) and Group 2 (n=221). Oral polio vaccine was given concomitantly to all subjects. Blood samples (pre-vaccination and 1 month after the third dose) were obtained from a subset of infants (Group 1, 73; Group 2, 22) for serological determinations. Local and general symptoms were recorded by parents on diary cards. 2614 diary cards (Group 1, 1966; Group 2, 648) were collected. There were no statistically significant differences in the incidence of local and general symptoms between groups. Pain such that the infant cried when limb was moved was reported in 0.6 and 0.2% in groups 1 and 2, respectively. Redness and swelling (>20 mm in diameter) were recorded between 2.1 and 3% in both groups. Fussiness preventing normal activities was the most frequently reported general symptom in both groups (1.6 and 1.9% in groups 1 and 2, respectively). Fever (rectal temperature >39.5 degrees C) was reported in 0.4% (Group 1) and 0.3% (Group 2). All subjects included in the immunogenicity analysis had seroprotective or seropositive titres to the diphtheria, tetanus, hepatitis B and pertussis components of the vaccines. About 99 and 100% of infants had anti-PRP titres > or =0.15 mcg/ml in groups 1 and 2, respectively. This study indicates that DTPa-HBV vaccine given in a single injection with a candidate Hib conjugate vaccine has a similar reactogenicity profile to that of two commercially available vaccines (DTPa-HBV, Hib) given in two simultaneous injections to infants 2, 4 and 6 months of age.

Haemophilus somnus was consistently isolated from vaginal discharges of dairy cows submitted from field cases of vaginitis, cervicitis and/or metritis in the KwaZulu-Natal Midlands during the period July 1995 - December 2000 and from the East Griqualand area in November/December 2000. The purulent vaginal discharges, red granular vaginitis and cervicitis, and pain on palpation described in these cases was very similar to that reported in outbreaks of H.somnus endometritis syndrome in Australia, Europe and North America. In all the herds involved in these outbreaks, natural breeding with bulls was employed. Although there was a good cure rate in clinically-affected animals treated with tetracyclines, culling rates for chronic infertility were unacceptably high. Employment of artificial insemination in these herds improved pregnancy rates in cows that had calved previously, but many cows that had formerly been infected failed to conceive.

Incidence of symptomatic bronchiectasis (BR) occurs in around 2% in patients with late rheumatoid arthritis (RA). Its seems that the association BR-RA could be a worsening factor for outcome of RA patients. A 58-year-old woman without dry syndrome, suffering from bronchial purulence over one year was admitted to the Department of Pneumology for hemoptysis and arthritis (knees, ankles, and wrists). Three prior episodes of inflammatory articular pain had occurred after transient bronchial purulence or pneumonitis. CT-scan showed bilateral bronchiectasis. Diagnosis of early RA was proved after the third episode of bronchial purulence related to a strain of Haemophilus influenzae. A strain of Coxiella burnetii was probably responsible for one of the three bronchial surinfections. Latex and Waaler Rose tests were transiently positive during the first episode, and became positive after the third one. At that time, RA was relevant in view of ARA criteria. Cyclic prophylactic antibiotic regimens could be proposed to patients suffering from RA-BR association, in contrast to the cases of patients with isolated BR. This approach could prevent destabilization of RA and reinforce of anti-rheumatic therapy. Activation and release of cytokines (NFk-B, TNF-alpha), and/or bacterial epitopes seems to be directly responsible for the articular destabilization.

Sinus puncture and aspiration is an invasive procedure that hinders patient enrollment in studies of acute bacterial maxillary sinusitis (ABMS). Pain and minor bleeding also limit its potential diagnostic utility in clinical practice. Cultures obtained by rigid nasal endoscopy were compared with those from sinus puncture and aspiration in 53 patients with ABMS; 46 patients were assessable. Considering recovery of Haemophilus influenzae, Moraxella catarrhalis, or Streptococcus pneumoniae from puncture and aspiration as the gold standard, endoscopy cultures demonstrated a sensitivity of 85.7% (95% confidence interval, 56.2-97.5), specificity of 90.6% (73.8-97.5), positive predictive value of 80% (51.4-94.7), negative predictive value of 93.5% (77.2-98.9), and accuracy of 89.1% (75.6-95.9). Ten adverse events related to puncture and aspiration occurred in 5 (9.6%) of 52 patients; there were no endoscopy-related adverse events. In our study, the largest to date, endoscopic sampling compared favorably with puncture and aspiration for identifying H. influenzae, M. catarrhalis, and S. pneumoniae in ABMS and produced less morbidity.

Little is known of the aetiology, serotypes or susceptibility of the pathogens causing non-resolving otitis media in children receiving care from specialists in private practice in developed or in developing countries. Increased access to antibiotics in the community amongst children receiving such private care in South Africa may be anticipated to lead to levels of resistance similar to those found in countries with similar models of private practice, such as the United States. This study was conducted to determine the aetiology of non-resolving otitis media in South African children receiving private care and to determine the antimicrobial resistance patterns and serotypes of the bacterial isolates. Middle-ear fluid was cultured from 173 children aged two months to seven years with non-resolving acute otitis media accompanied by persistent pain or fever who were referred to otorhinolaryngologists for drainage of middle-ear fluid within 14 days of the start of symptoms. While 92 per cent of the children had recently received antibiotics and 54 per cent were currently receiving them, bacteria were isolated from 47 children (27 per cent). Streptococcus pneumoniae was the most common pathogen (35), followed by Haemophilus influenzae (nine), Staphylococcus aureus (six), Moraxella catarrhalis (two), Streptococcus pyogenes (two) and Pseudomonas aeruginosa (one). Two isolates were identified in each of eight children. Antimicrobial resistance to one or more antibiotics was found in 33/35 (94 per cent) of the pneumococci isolated, with resistance to penicillin in 86 per cent, resistance to trimethoprim-sulfamethoxazole in 54 per cent and to erythromycin and clindamycin in 69 per cent and 57 per cent, respectively. The pneumococcal serotypes found were 19F (28 per cent), 14 (26 per cent), 23F (23 per cent), 6B (nine per cent), 19A (87 per cent), and four (three per cent). Children with a bacterial pathogen isolated were younger (mean age of 17 months) than children from whom no bacteria were isolated (mean age of 23 months; p = 0.03). Isolation of a pneumococcus was also significantly associated with younger age (mean = 16 months versus 22 months, p = 0.03), the presence of fever (OR = 2.15, p = 0.049), and having one or more prior episodes of otitis media within the six months before tympanocentesis (OR = 7.72, p = 0.03). Almost all pneumococci isolated from non-resolving acute otitis media in this community are antibiotic-resistant and should be considered especially in young children who have failed previous therapy and who have non-resolving pain or fever.

Primary vaccination of infants with diphtheria-tetanus-acellular pertussis-hepatitis B recombinant (adsorbed)-inactivated poliomyelitis-adsorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib; Infanrix hexa)-inactivated poliomyelitis-absorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib) refers to Infanrix hexa trade mark.) provided high levels of seroprotection against diphtheria toxoid, tetanus toxoid, poliovirus 1, 2 and 3, pertussis antigens (pertussis toxoid, filamentous haemagglutinin and pertactin), hepatitis B virus surface antigen and H. influenzae polyribosyl-ribitol-phosphate (PRP) antigen. Most infants (97%) had anti-PRP levels >/=0.15 micro g/mL after a booster dose at 18 months. Primary vaccination with the DTPa-HBV-IPV/Hib vaccine produced a similar immune response to that with two different pentavalent plus monovalent vaccine combinations. Coadministration of DTPa-HBV-IPV/Hib vaccine and a heptavalent pneumonococcal conjugate vaccine resulted in a high level of seroprotection and was well tolerated. Primary or booster vaccination with DTPa- HBV-IPV/Hib vaccine was well tolerated. Commonly reported local adverse reactions included redness, pain and swelling. Systemic symptoms were usually mild to moderate, and included fussiness, fever, restlessness and sleepiness.

Acute otitis media is defined as eardrum inflammation associated with middle-ear effusion and acute signs and symptoms. Viruses are the primary pathogens, and bacterial superinfection is common. Pneumococci and Haemophilus influenzae are the most frequently isolated bacterial pathogens. Recovery is usually rapid, though somewhat slower in children under 2 years of age. The only benefits of antibacterial chemotherapy are a marginal reduction in the duration of pain and use of analgesics. Antibacterial therapy has no effect on the risk of relapse, medium term auditory outcome in children, or complications. It does, however, increase the risk of becoming a carrier of resistant strains

An open, randomised, multicentre trial was performed to compare the reactogenicity and safety profile of the administration of a hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated polio (DTPa-HBV-IPV) vaccine administered in one injection mixed with Haemophilus influenzae type b (Hib) conjugate vaccine (Group 1) with that of a pentavalent DTPa-IPV vaccine mixed with a Hib vaccine (DTPa-IPV/Hib), simultaneously administered with HBV (Group 2) in two injections in opposite thighs, as a primary vaccination course, to healthy infants at 2, 4 and 6 months of age. A total of 235 completed the study, 120 from Group 1 and 115 from Group 2. Blood samples (pre-vaccination and 1 month after the third dose) were obtained from a subset of infants (Group 1: 40; Group 2: 31) to assess the immune response to vaccination. Local and general solicited symptoms were recorded by parents on diary cards. Seven hundred and five diary cards (Group 1: 360; Group 2: 345) were collected. The clinically relevant and most commonly reported local reaction was pain (infant cried when the limb was moved) in 2.5% (Group 1) and 1.2% (Group 2) of diary cards. Fever was more frequently reported in Group 1 (21% of diary cards) than in Group 2 (12% of diary cards). However only 3 and 2% of doses in Groups 1 and 2, respectively, were responsible for a rectal temperature between 38.6 and 39.5 degrees C and only one case (Group 2) had > or =39.5 degrees C. Other clinically relevant general symptoms were rarely recorded: irritability (2-2.8%), loss of appetite (0.3-0.6%) and drowsiness (0.3-0.3%). All subjects included in the immunogenicity analysis had seroprotective titres to diphtheria, tetanus, polio virus types 1 and 3, Hib. Almost all subjects were seroprotected for anti-polio type 2 and hepatitis B (with the exception of 1 subject in Group 1 for each antigen). The vaccines response rates to pertussis antigens were over 97 and 90% in Groups 1 and 2, respectively. This study shows that, from a clinical perspective, the DTPa-HBV-IPV/Hib vaccine given in a single injection has a similar reactogenicity and safety profile to that of two licensed vaccines (DTPa-IPV/Hib, HBV) given in two simultaneous injections to infants at 2, 4 and 6 months of age. This is a valuable advantage, since in some countries, such as Spain and the UK, an additional injection (for the administration of meningococcal C conjugate vaccine) has been recently included in the infants' vaccination calendars.
